Transporting device with panel truck
A transporting device has a container, a panel member, a wheel frame and two wheels. The panel member has a plate and two first linkages pivoted on the plate and on lateral sides of the container respectively. The wheel frame has two second linkages pivoted on mid sections of the first linkages respectively and the wheels are mounted on the second linkages. The panel member is moved between a collapsed position, in which the plate is attached on the container and the wheels are moved to the lateral sides of the container respectively, and an expanded position, in which the plate and the wheels are moved apart from the container. The container is provided with a shaft with a handle and a front wheel on opposite ends to control the direction of the transporting device to go. A motor and a transmission device are provided to drive the transporting device to run.

1. Field of the Invention
The present invention relates generally to a transporting device, and more particularly to a transporting device with the panel truck.
2. Description of the Related Art
The combination of a case and a transporting device provides a convenient way of transportation. A panel truck is pivotally mounted on a bottom side of a case of a conventional luggage. To collapse the luggage, the panel truck is folded upwards and attached on a back side of the case. To expand the luggage, the panel truck is moved downwards and the case stands upright in front of the panel truck. The case is provided with a handle to be held by user to allow him/her standing on the panel truck.
The conventional luggage simply provides the panel truck pivoted on the case, so that the wheels of the truck still are exposed in the collapsed condition. The exposed part of the panel truck makes an incomplete view of the luggage and it interferes with user to carry the luggage. The case has a recess to receive the pivot arms, the panel and the wheels of the panel truck. The recess reduces the volume of the case to store goods. The recess is provided at a middle portion of the case, so that a large good is hard to be stored in the case. The conventional luggage provides the panel truck having small wheels. The small wheels are good for the collapsed condition but reduce the balance in the expanded condition.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a transporting device, which less space is needed to receive the truck panel.
The secondary objective of the present invention is to provide a transporting device, which has a well balance in the expanded.
According to the objectives of the present invention, a transporting device comprises a container. A panel member has a plate and two first linkages. Ends of the first linkages are pivoted on the plate and on opposite lateral sides of the container respectively to be moved between a collapsed position, in which the plate is attached on the container, and an expanded position, in which the plate is moved apart from the container. A wheel frame has two second linkages and a stop member. Ends of the second linkages are pivoted on mid sections of the first linkages respectively and the stop member is fixed on the second linkage to sustain the plate while the panel member is moved to the expanded position. Two wheels are mounted on the second linkages respectively for free rotation. The wheels are moved to the lateral sides of the container respectively via the second linkages while the panel member is moved to the collapsed position and the wheels are moved apart from the container via the second linkages while the panel member is moved to the expanded position.
As shown in FIGS. from
The container 10 has a front side 11, a back side 12, a top side 13, a bottom side 14 and two lateral sides 15. The container 10 has a chamber therein, a depression portion 161 on the top side 13 and a hole 16 from a bottom of the depression portion 161 to the bottom side 14. The container 10 further has an aperture 17 at each of the lateral sides 15 (seeing
The panel member 20 has a plate 21, two first linkages 22 and two torsional springs 23. Ends of the first linkages 22 are pivoted on the plate 21 and on the lateral sides 15 of the container 10 respectively. The plate 21 and the first linkages 22 are moved upward to a collapsed position, in which the plate 21 is attached on the back side 15 of the container 10, and are moved downwards to an expanded position, in which the plate 21 moves distal to the container 10. The torsional springs 23 is received in the aperture 17, in which the ends of the first linkages 22 are pivoted, to urge the first linkages 22 moving to the collapsed position in initial.

The driving device 60 has a motor 61, a transmission device 62 and a power (not shown). The transmission device 62 connects the motor 61 to the wheel 30 to drive the wheels 30 running. The power provides electricity to the motor 61.
In the collapsed position, the plate 21 is folded and attached on the back side 12 of the container 10 and the wheel 30 are moved to the lateral sides 15 of the container 10 respectively. In the expanded position, the plate 21 is moved downwards to a horizontal position and the wheels 30 are moved to opposite sides of the plate 21 respectively and the stop member 42 sustains the plate 21.
As shown in
As shown in
The wheels 30 are folded to the lateral sides 15 of the container 10 that does not take any space of the chamber of the container 10 to store goods. The diameters of the wheels 30 can be equal to the width of the lateral side 15, which means the wheels 30 of the present invention are bigger to provide a balance condition. The wheels 30 always have portions extruded out of bottom side 14 of the container 10 in both of the expanded condition and collapsed condition (seeing
In the specification of the present invention, we only provide a few of preferred embodiments. The scope of the present invention should not be restricted in the preferred embodiment. Any equivalent designation should be still in the scope of the present invention.
Claims
